( Fig. 13–16 )

Description. Female. Integument mostly black; mouthparts reddish brown except nearly black palpomeres (apex of labial palpomeres I–II and maxillary palpomeres I–III narrowly yellowish brown); anteclypeus dark brown close to postclypeus, orangish brown on remaining surface; posterior half of labrum reddish brown; gulamentum mostly brown; base of antennomere III orangish brown; antennomeres IV–VIII pale yellow anteriorly (more orangish depending on light intensity), this area gradually shorter toward VIII, dark brown posteriorly; antennomeres IX–XI dark brown. Coxae partially dark reddish brown; protrochanters pale yellow; meso- and metatrochanters dark reddish brown.

Head. Frons somewhat coarsely, abundantly punctate toward antennal tubercles, finer, sparser toward postclypeus, especially laterally; glabrous except superior area between eyes with dense, nearly black pubescence (this area triangularly projected toward central region); with minute whitish seta within punctures in glabrous area; with long, erect dark setae close to eyes. Vertex and area behind eyes somewhat finely, sparsely punctate (punctures coarser behind lower eye lobes); with dense black pubescence obscuring integument, except glabrous central area between antennal tubercles, nearly glabrous median groove from area between upper eye lobes, and not obscuring integument behind lower eye lobes; with long, erect, sparse dark setae on vertex and area behind upper eye lobes. Genae almost smooth; with dense, transverse white pubescent macula posteriorly close to lower eye lobe, glabrous on remaining surface; with a few long, erect dark setae near white macula. Antennal tubercles with black pubescence (more dark brown anteriorly) not obscuring integument, with long, erect dark setae interspersed. Postclypeus not distinctly separated from frons; finely sparsely punctate in wide central area (punctures sparser in center of this area), nearly smooth laterally; glabrous, with a few long, erect brownish setae centrally near anteclypeus. Labrum coplanar with anteclypeus in posterior half, oblique in anterior half; with transverse row of fine punctures in posterior half close to oblique area, with long, erect yellowish-brown seta in nearly all punctures. Gulamentum smooth, glabrous. Distance between upper eye lobes 0.37 times length of scape (0.30 times distance between outer margins of eyes); in frontal view, distance between lower eye lobes 0.78 times length of scape (0.62 times distance between outer margins of eyes). Antennae 1.25 times elytral length, almost reaching elytral apex. Scape with dense, bristly black pubescence, with long, erect black setae interspersed throughout in posterior 2/3. Pedicel with black pubescence, not obscuring integument dorsally, somewhat bristly, with long, erect black setae interspersed ventrally. Maximum diameter of antennomere III almost twice length of pedicel; with dense, erect black setae throughout, and longer black setae interspersed. Antennomeres IV–VIII with sparse whitish pubescence in pale yellow area, brownish in dark area (partially interspersed with whitish setae ventrally); with long, erect, sparse black setae ventrally. Antennomeres IX–XI with dark pubescence obscuring integument, with short, erect yellowish setae interspersed; ventral surface of IX may or may not have long, black erect setae (present only on left antennomere in holotype). Dorsal apex of antennomeres III–X with a few long, erect black setae (shorter toward X). Antennal formula (ratio) based on length of antennomere III: scape = 0.67; pedicel = 0.12; IV = 0.62; V = 0.33; VI = 0.27; VII = 0.25; VIII = 0.21; IX = 0.19; X = 0.17; XI = 0.24.

Thorax. Pronotum coarsely, sparsely punctate, punctures coarser, more abundantly posteriorly; with dense black pubescence partially obscuring integument, bristly in some areas, with long, erect black setae interspersed. Sides of prothorax coarsely, somewhat sparsely punctate; pubescence as on pronotum. Prosternum coarsely, abundantly punctate; with grayish-white pubescence not obscuring integument, except longitudinal, narrow white pubescent band on each side. Prosternal process with sparse grayish-white pubescence; narrowest area 0.15 times width of procoxal cavity. Mesoventrite with sparse grayish-white pubescence centrally, denser, dark laterally. Mesanepisternum and mesepimeron with dense blackish pubescence. Mesoventral process with whitish pubescence not obscuring integument. Metanepisternum and metaventrite with dense nearly black pubescence, except glabrous central area of metaventrite, and bristly yellowish-white pubescence posteriorly close to glabrous area. Scutellum with nearly black pubescence partially obscuring integument. Elytra. Coarsely, abundantly punctate in basal third, punctures gradually finer toward apex; with dark brown pubescence not obscuring integument (more grayish depending on light intensity); with long, erect, somewhat abundant dark setae interspersed; dorsal carina well-marked; apex individually rounded, sutural angle absent. Legs. Femora with grayish pubescence not obscuring integument (appearing to be darker dorsally and laterally due to integument color and light intensity), with long, erect setae of same color interspersed, more abundant ventrally. Tibiae with bristly dark brown pubescence not obscuring integument, with long, erect dark brown setae interspersed; protibiae with a few erect yellowish-white setae near apex.

Abdomen. Ventrites with yellowish-white pubescence not obscuring integument (more grayish depending on light intensity), with long, erect setae of same color interspersed. Apex of ventrite V emarginated centrally, with abundant, long yellowish setae.

Dimensions in mm. Total length 9.05; prothoracic length 1.25; anterior prothoracic width 1.65; posterior prothoracic width 1.70; humeral width 2.60; elytral length 6.75.

Type material. Holotype female from MEXICO, MEXICO: San Antonio Albarranes , 23.VIII.1994, B.C. Kondratieff col. ( TAMU, formerly CSUC).

Etymology. It is a pleasure to name this species for Prof. Boris C. Kondratieff, educator and curator at CSUC, who has helped the second author tremendously for the last quarter century.

Remarks. Schmidarius kondratieffi sp. nov. differs from S. usingeri by the absence of yellow pubescence in the center of the head, pronotum and scutellum (present in S. usingeri ), and femora entirely dark (bicolorous in S. usingeri ). It differs from S. grisescens and S. flavescens by the absence of yellow pubescence on the sides of the head and pronotum (present in both species).
